'Hot Air' is Hull #3 in that vintage and belonged to a chap down in Penzance. He has subsequently retired and always complained that she was way too fast for him?!! He then sold her to a marine engineering workshop in Foie who re-engined her with an Evinrude Ficht 250hp - they subsequently sold it to the current owner, Paul **** who lives in Cowes. When I last spoke to him he told me he was very happy with her - I also checked that the valves did not go through the cabin as they used to in those days
